The Attack at Bridge Bay Campground
On the evening of July 10, 2026, 65-year-old Carl Isom-McDaniel was walking with his 13-year-old grandson along the roadway at Yellowstone National Park’s Bridge Bay Campground in Wyoming. After stopping to photograph a massive bull bison from roughly 100 yards away, a passing truck honked, agitating the animal. The bison charged, head-butted Isom-McDaniel, and propelled him about eight feet into the air before he landed on the ground.
Immediate Medical Response
Park emergency medical personnel arrived within minutes, stabilized the victim, and transported him to a nearby hospital. Surgeons repaired a femur broken in four places and a shattered hip. By the following Monday, Isom-McDaniel was walking and reported he was “in good spirits.”
Eyewitness Account
Former Army combat photographer Mike MacLeod captured the incident on video. He stopped filming when the bison stood over the injured man, fearing a gore, and ran toward the animal, shouting and waving his arms to appear larger. MacLeod later said he was “really afraid he was going to gore the guy on the ground.”
Bison Behavior and Seasonal Factors
Biologists note that the attack occurred during the rutting (mating) season, which runs from June through September. Male bison can become highly territorial and display “extra energy and aggression” while competing for dominance. MacLeod described the animal as “agitated, pissed off, and charging anything and everything.”
Park Safety Regulations
Yellowstone regulations require visitors to keep a minimum distance of 75 feet (approximately 23 meters) from bison, elk, and bighorn sheep, and at least 100 yards from apex predators. Enforcement across the park’s 2.2 million acres relies on signage and visitor compliance; the sheer size of the landscape makes constant monitoring difficult.
Official Statements & Responses
The National Park Service confirmed that park rangers responded promptly, provided medical aid, and emphasized that “visitors must maintain a respectful distance from bison, especially during mating season.” The agency reiterated existing distance guidelines and noted that the incident underscores the importance of adhering to them.
Criticism & Calls for Stricter Enforcement
Conservation analysts argue that “selfie-induced conflict” is rising as tourists breach buffer zones to capture photos. Proposals under review include higher fines for proximity violations, increased ranger patrols, and the deployment of drone-based monitoring to issue pre-emptive evacuation orders near high-traffic campsites.
Data & Statistics
- Adult male bison can weigh up to 2,000 pounds and run up to 35 mph, three times faster than an average human.
- Bison are responsible for over 60 % of wildlife-related injuries at Yellowstone over the past decade.
- The park receives millions of visitors annually, creating frequent points of contact between people and megafauna.

What’s Next
Yellowstone officials are reviewing spatial-management strategies, including possible drone surveillance and revised penalty structures, to reduce future human-bison collisions while preserving visitor access to the park’s iconic wildlife.
